WordWand vs Kerlig: Which Mac AI Writing Assistant Should You Choose in 2026?

Both WordWand and Kerlig are native macOS apps that put AI writing tools in your menu bar. They share the same core idea — select text, trigger a shortcut, and let AI do the work. But they take very different approaches to what an AI writing tool should be.

Kerlig leans into flexibility: 350+ AI models, a chat interface, image analysis, and full BYOK (Bring Your Own Key) support. WordWand leans into completeness: voice dictation, text-to-speech, podcast mode, and translation — all bundled together.

Here is how the two compare across the dimensions that matter most.

How They Work

Kerlig

Kerlig is a native macOS menu bar app activated with Option+Space. It works in two modes: an inline mode that processes selected text in any app, and a chat mode that lets you converse with AI about documents, images, and web content. The chat interface preserves history and supports citations.

The defining feature is its BYOK model. Kerlig supports 350+ AI models across OpenAI, Anthropic, Google, Groq, Ollama, LM Studio, Apple Foundation Models, and more. You bring your own API keys and choose which model to use per task.

Kerlig costs $49 one-time for a Basic license (1 Mac) with no recurring fees.

WordWand

WordWand is a native macOS menu bar app that works through a single keyboard shortcut. Select text in any app, press the shortcut, and choose an action — fix grammar, translate, rewrite, adjust tone, generate text, or run a custom prompt. The result replaces your selection inline.

Beyond text processing, WordWand bundles voice dictation, text-to-speech with podcast mode, translation in 40+ languages, and task extraction.

WordWand has a free tier (5,000 words/month, all features) and Pro at $10.99/month.

Key Differences

Voice Dictation

WordWand includes built-in voice dictation. Hold the dictation shortcut, speak, and your words are transcribed and inserted wherever you are typing. You can immediately fix grammar or adjust tone on the dictated text — the entire speak-to-polished-text workflow happens in one tool.

Kerlig does not offer voice dictation. To dictate, you would need a separate app like Superwhisper or Wispr Flow, then use Kerlig to polish the result.

For users who dictate emails, Slack messages, or long-form content, this is a significant difference.

Text-to-Speech and Podcast Mode

WordWand can read any selected text aloud with natural-sounding voices. The standout feature is podcast mode, which converts text into a two-person conversation — two voices discussing your content as if it were a podcast. Useful for reviewing documents, studying, or consuming long content.

Kerlig does not offer text-to-speech or any audio output.

Translation

WordWand has a dedicated translation feature supporting 40+ languages. Select text, translate, and the translation replaces the original text inline. No tab switching, no copy-pasting.

Kerlig can translate text through its AI models, but it does not have a dedicated translation feature with language selection. The quality depends on which model you use and how you prompt it.

Chat Interface and Vision

This is where Kerlig has a clear advantage. Its chat interface lets you have back-and-forth conversations with AI, analyze images, discuss documents and web pages, and maintain chat history with citations. Kerlig supports reasoning models with visible chain-of-thought.

WordWand is action-based, not chat-based. You select text, run an action, and get the result. There is no conversational interface or image analysis. This makes WordWand faster for quick text tasks but less suited for exploratory AI conversations.

AI Model Selection

Kerlig supports 350+ models across 12+ providers. You bring your own API keys and can switch models per task. This includes local models via Ollama and LM Studio — meaning some tasks can run completely offline and privately.

WordWand uses its own cloud AI models. You do not choose or manage models. This is simpler — no API keys to configure — but offers less flexibility.

iOS App

WordWand is building an iOS app with a keyboard extension — coming soon.

Kerlig is Mac-only.

Pricing

Plan	WordWand	Kerlig
Free	5,000 words/month, all features	None (14-day money-back guarantee)
Paid	$10.99/month (Pro, 50K words)	$49 one-time (Basic, 1 Mac)
Higher tiers	Up to 2M words/month from $14.99/mo	$79 one-time (Pro, 2 Macs)
Team	—	$297 one-time (10 Macs)

Kerlig's one-time pricing is appealing if you dislike subscriptions. But note that Kerlig's paid plans do not include AI model costs — you pay for API usage separately. WordWand's subscription includes everything.

Privacy

WordWand processes text in real-time without storing it on servers. Audio from voice dictation is deleted immediately after transcription. Your content is never used to train AI models.

Kerlig sends messages directly to your chosen AI provider, then stores them encrypted on your Mac. If you use local models via Ollama or LM Studio, your data never leaves your machine.

Who Each App Is For

Kerlig fits best if you want maximum flexibility over AI models, need a chat interface for document and image analysis, prefer one-time pricing, or want to run AI locally via Ollama. It is a power-user tool that rewards configuration.

WordWand fits best if you want a complete writing toolkit — dictation, grammar, translation, TTS, and AI writing — in one app with zero configuration. The free tier and subscription model that includes everything make it the simpler, more feature-complete option for everyday writing workflows.
